| -- |
| -- OBJECTIVE: |
| -- Check that if the original protected entry call was a conditional |
| -- entry call, the call is cancelled if a requeue-with-abort of the |
| -- call is not selected immediately. |
| -- Check that if the original protected entry call was a timed entry |
| -- call, the expiration time for a requeue-with-abort is the original |
| -- expiration time. |
| -- |
| -- TEST DESCRIPTION: |
| -- In this test the main task makes a variety of calls to the protected |
| -- object Initial_PO. These calls include a simple call, a conditional |
| -- call, and a timed call. The timed calls include calls with enough |
| -- time and those with less than the needed amount of time to get through |
| -- the requeue performed by Initial_PO. |
| -- Initial_PO requeues its entry call to Final_PO. |
| -- Final_PO does not accept the requeued call until the protected |
| -- procedure Ok_To_Take_Requeue is called. |
| -- A separate task, Delayed_Opener, is used to call Ok_To_Take_Requeue |
| -- after a delay amount specified by the main task has expired. |
